Who's responsible...?

I bought data yesterday morning at 08:00 and the app told me the transaction is being progressed... So I did it again... still same message. By 12:00 yesterday I had not received my data so I called Vodacom and they said it's a problem with FNB, I called FNB and they say it's a Vodacom delay. Who is responsible? I called last night and still the same issues... no one knows who's responsible. Give me my data or reassure me the money won't be deducted if I try again. I don't have cash to keep buying data that had an expiry date. F L I P P E N H E L L Give me my data!!!!!
